FIBER-RUBBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 315,666, dated April 14, 1885.

Application filed August U, 1884.

To all whom it may concern: 1

Cronly, in the county of Columbus and State of North Carolina, have invented a new and lmproved Fiber-Rubbing Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for rubbing vegetable liber, especially pine-needles, forthe purpose of rendering the iiber useful for up holstery purposes or for spinning.

The invention consists in the combination,

i with a series of spirally or transversely fluted rollers, of smaller spirally or transversely iiuted rollers above them, and of additional spirally or transversely iiuted rollers which are moved in the direction of their length while revolving. rlhe brons material is passed in between the several rollers which are revolved. Jets of hot water are delivered upon the rollers and the material between them. The water is then pressed from the material by suitable wringerrollers, and the material is then picked or carded by a suitable picker or carder.

The invention also consists in various parts and details and combinations of the same, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a plan view of my improved fiber-rubbing machine. Fig. 2 is a longitudinal sectional elevation of the same, the frame of the machine not being shown. Fig. 3 is a cross-sectional elevation of the saine on the line .fr x, Fig. 1. Fig. 4 is an end elevation of the same.

In aframe, A, a series of horizontal rollers, B, are jonrnaled parallel with each other in such a manner that their side edges are almost in contact, the said rollers being spirally tinted, one half of each being luted from right to left and the other from left to right, as shown. On the ends of the shafts B of the said rollers B bevel cog-wheels C are mounted, which engage with bevel oog-wheels D on a shaft, E, at right angles to the several wheels B. At each roller B a roller, F, is held parallel with and (Xo model.)

a short distance from the saine, the several rollers F being also spirally fluted in opposite directions to the lutings of the rollers B, and the liutings of the rollers F being much smaller than the lutings of the rollers B. On the ends of the shafts F of the rollers F bevel cog Vwheels G are mounted, which engage with ybevel cog-wheels H on a shaft, J, parallel with and above the shaft E. On the shaft J a bevel cog-wheel, I, is mounted, which engages with a bevel-pinion, l', on a shaft, l2, provided with a belt-pulley, l, over which a belt, K, passes, which also passes over a pulley, K', on the main drivingshaft L, on which are mounted the xed and loose pulleys L L2. On the shaft J is mounted a pinion, e, engaging with acogwheel, b, on a shaft, c, ou which is also mouuted a pinion, d, engaging with a coglwheel, e, on the shaft E, whereby the shaft E is operated from the shaft J, but at a much slower speed. Between the rollers F rollers M are arranged, which are held close to the two adjoining roll ers B, and are slightly lower than the rollers F, the said rollers M being also fluted spirally and in one direction, their flutiugs being about the same size as the fiutings of the rollers B. The shafts M of the rollers M each have one end connected with a ring or strap, g, surrounding an eccentric disk, lz, on a shaft, t', provided at one end with a bevel cog-'wheel, j, engaging with a bevel cog-wheel, k, on the :main driving-shaft L. The opposite ends of the shafts M are squared, and pass loosely through cog-wheels N', held to revolve in one of the side pieces of the frame A, and engaging with cog-wheels N on the shafts Bl of the rollers B, whereby the said rollers M are revolved.

At one end of the machine an endless belt or apron, O, is arranged, which passes over two rollers, O O?, and above the roller O a presser-roller, P, is arranged. Between the first roller B and the rollers O and l? two longitudinally1luted rollers, Q, are arranged for the purpose of laying the fibers straight and pressing them. At the other end of the machine two rubber wringer-rollers, B B, are arranged for pressing the water out of the liber, and adjoining the rollers R two feedrollers, S, having prongs on their surfaces, are arranged for feeding the fiber to the pickerroller T.

Above the upper feed-roller, S, a pronged Y grated by the rollers.

rollers Q, which soften the needles and lay them straight. The needles are then carried over the rollers B, and are pressed and rubbed between the rollers B and F and the rollers 'B and M, which rollers M also move transversely to the machine, thereby rubbing the needles and rendering them very fibrous. The hot water delivered from the'pipes U and W softens the needles, and also washes off any material that has been loosened and disinte- The wringer-rollers R press out all the surplus water, and then the pine-needles are picked or carded vby the picker-roller T. The feed-rollers S hold the needles while the picker is picking'them, and

the roller V cleans the feed-rollers.

The machine operates very rapidly, and by means of it a large quantity of pine-needles or other brous material can be treated in a very short time. The ibrous material that leaves the roller T is baled in theusual manner, or recarded and dried, according to the purpose for which it may be used.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a liber-rubbing machine, the combination, with two or more spirally or transversely luted rollers, of smaller transversely or spirally rluted rollers adjacent to them, and of additional transversely or spirally iiuted rollers adjacent to the lower rollers, substantially as herein shown and described.

2. In a fiber-rubbing machine, the combination,.with two or more spirally or transversely uted rollers B, of the smaller transversely or spirally fluted rollers F, adjacent to them, the spirally or transversely tluted roll- 4 -e'rs M, adjacent to the rollers B, between the rollers F, and devices for reciprocating the rollers M at the same time that t-hey are being revolved, substantially as herein shown and described.

3. In a ber-rubbing machine, the combination, with a series of spirally or transversely iiutedrollers, B, of the transversely or spirally `luted rollers F above the rollersl B, the spirally or transversely uted rollers M above the rollers B and between therollers F, the wringer-rollers B, and the picker-roller T, substantially as herein shown and described.

4. In a fiber-rubbing machine, the combination, with a series of spirally or transversely iiuted rollers, B, of the transversely or spirally luted rollers F above the rollers B, the spirally or transversely iiuted rollers M above the rollers B and between the rollers F, the wring errollers R, the feed-rollers S, and the pickerroller T, substantially as herein shown and described.

In a ber-rubbing machine, the combination, with the spirally or transversely tluted rollers B,- of the smaller transversely or spirally fluted rollers F above them, the transversely or spirally iluted rollers M between the rollers F, the wringer-rollers B, the pickerroller T, the longitudinally-timed rollers Q, the belt O, and the pipes U W, for delivering jets of hot water upon the several rollers and the material between them, substantially as herein shown and described.

8. In a ber-rubbing machine, the combination, with the rollers B, F, and M, of the gearing for revolving the rollers, the shaft fi, the eccentric disks h on the same, and the rings g surrounding the said disks, which rings are connected with the shafts of the rollers M, substantiallyas herein shown and described.
